问题
Visual Studio 2019 has the very useful facility to edit the project's csproj file without first unloading the project via the context menu (or 'right click menu' to aid the search feature):
However, I'm finding this isn't working intermittently, a lot of the time it just does nothing when I click the option. Later it will start working again without restarting the project. This is for a solution with multiple .NET Core Web projects and multiple .NET Standard libraries.
Does anyone know the cause of this?
(Possibly related: I've also been having issues with saving a csproj file causing my changes to be undone as per this question.)
